* proto: rebuild the proto files from the spec repository

* remove proto checks

This PR implements the proto changes made in https://github.com/tendermint/spec/pull/352, removing the legacy messages that were used in the pex reactor.

## Description

- bump gogoproto (1.3.2)
- regenerate proto files

Closes: #XXX

## Description

In protobuf `[]byte` is varint encoded. When adding txs to the block we were not taking this into account. 


Closes: #XXX

Reorganizes the Protobuf schemas. It is mostly bikeshedding, so if something is contentious or causes a lot of extra work then I'm fine with reverting. Some Protobuf and Go import paths will change.

* Move `abci/types/types.proto` to `abci/types.proto`.

* Move `crypto/keys/types.proto` and `crypto/merkle/types.proto` to `crypto/keys.proto` and `crypto/proof.proto`.

* Drop the use of `msgs` in filenames, as "message" is a very overloaded term (all Protobuf types are messages, and we also have `message Message`). Use `types.proto` as a catch-all, and otherwise name files by conceptual grouping instead of message kind.

Fixes some minor issues with Protobuf enums, not likely to break anything.

Branched off of #5096, rebase to `master` before merging.

## Description

This PR moves all proto files under one dir (`/proto`). The script to generate adding functionality to copy the files that still need to be in the same place. (abci & rpc)

renames every proto package from `tendermint.proto.<pkg_name>` to `tendermint.<pkg_name>`

Removes unneeded types in privval proto directory

Closes: #XXX

* test-vectors for backwards compatibility:

 - copy & paste test-vectors from v0.33.5 to ensure
 backwards compatibility for vote's SignBytes

* WIP: everything besides time seems to match :-/

* almost

* Found the culprit: field nums weren't consecutive ints ...

* fix order of partset header too

* this last votes-related test can easily be fixed

* some minor changes and fix last failing test

* move proto types back to stdtime, fix various linting

* use libs/protoio

* remvoe commented code

* add comments

* fix tests

* uncomment testscases

* dont ignore error panic

* fix signable test

* fix happy path testing

* fix comment

## Description

This PR removes simple prefix from all types in the crypto/merkle directory.

The two proto types `Proof` & `ProofOp` have been moved to the `proto/crypto/merkle` directory.

proto messge `Proof` was renamed to `ProofOps` and `SimpleProof` message to `Proof`. 

Closes: #2755

## Description

these proto files are meant to help unblock ibc in their quest of migrating the ibc module to proto.

Closes: #XXX

- regenerate proto using docker image
- on proto breakage a different compiler is used to generate some more helper functions, on master the same one os not used, reverting back to the one used on master to undo further confusion till proto-breakage is merged
